Electronic Waste
Today the quantity of electronic device have been increasing
After electronic waste have increased considerably
Electronic waste or E-waste
Electronic waste or E-waste
is an electric appliance and electronic device that expired and obsolete so it was left. In 2019 among of electronic waste around the world have increased considerably up to 53.6 million metric ton and only 17.4% was gathered to recycle. In addition techno advancement make people change electric appliance more often or because the mean of service life are diminish every year. In 1997 the service life of computer has 6 years but in 2005 the service life of computer has only 2 years left and the service life of a phone can be lower than 2 years and it has a tendency to lower than now

Ｗhat is Electronic waste?
Ｗhat is Electronic waste?
Electronic waste (English: e-waste or e-scrap), or electronic waste (English: Waste Electrical and Electronic Equipment, WEEE) refers to electrical or electronic equipment that is discarded and no longer used. In some developing countries , the phenomenon of e-waste is very serious, and the environmental pollution caused by it threatens the health of local residents.
What cause the increase of the Electronic Waste?
What cause the increase of the Electronic Waste?
The rapid update of technology, the rapid replacement of products (such as tapes , software, MP3 ), the declining prices of electronic products, and the elimination cycle planned during product design have all led to the rapid growth of global e-waste.
The main components of e-waste
The main components of e-waste
A large number of substances found in e-waste include :

Recycling
The e-waste recycling industry is already a huge and fast-growing industry in developed countries. The progress of this industry involves the transformation of some companies from energy-intensive downcycling (English: downcycling , such as the traditional recycling industry) to the e-waste recycling industry, through reuse and reprocessing to achieve the desired goals. The recycling of electronic waste has many benefits in environmental protection and society.
such as
reducing the demand for new products and new raw materials
reducing the water and power resources required for production
reducing the cost of packaging
making resources in the society
The allocation is more reasonable; and the use of garbage dumps is reduced.
Processing technology
In some developed countries, the first step of e-waste disposal involves disassembling discarded electronic devices and breaking them down into metal casings, power supplies, circuit boards, plastic components, and other parts.
This process is usually performed manually. A typical example is the NADIN electronic waste processing plant in Novi Iskar, Bulgaria-the largest organization of its kind in Eastern Europe. The advantage of manual operation is that people can identify and retain those parts that can still work or can be repaired, including chips, transistors, random access memory ( RAM ), etc.; the disadvantage is that artificial production is harmful to health , Unsafe, but workers get lower wages.
In other large-scale processing systems, there is a storage tank for transferring electronic waste that is about to be decomposed into fragments. Through scanning instruments and shredders, these wastes are broken down into separated metal fragments and plastic fragments. The plastic part is screened out and sold to plastic recyclers for further processing. But in the process of machine breaking and scanning.
E-Waste Management in Taiwan
E-Waste Management in Taiwan
Taiwan’s 4-in-1 Recycling Program, enacted in 1997. The program aims to reduce municipal solid waste, increase recycling, and improve the recycling industry. Under an Extended Producer Responsibility (EPR) program, manufacturers and importers of new goods have to pay recycling fees to the Environmental Protection Administration Taiwan (EPAT) and offer recycling collection from consumers. The fees collected from these manufacturers feed into the Recycling Fund, which subsidizes collection and recycling.
The program works through the active engagement of four key actors.
Community residents separate and deposit their waste at collection points.
Private recyclers and collectors buy regulated recyclable waste (RWW), including e-waste
Municipalities and local governments organize collection teams.
Recycling Fund subsidizes municipal recyclable waste collection and other private recyclers that meet EPAT standards.
